Plant-based products account for the vast majority of items in the emerging alternative-seafood space, but the outlook for cell-based seafood products is much more promising and has been strengthened this year by two policy rulings in the United States and the Netherlands.

The moves are significant, as is the investment in cell-cultured seafood companies, because they are fueling a sector that has the potential to seriously reshape the global supply chain in the coming years.

In June, the United States became the second country in the world -- followed by Singapore in 2020 -- to allow the sale of lab-grown meat, after regulators approved the sale of two cultivated meat products, produced by cell-cultured seafood makers Upside Foods and Good Meat.
